A concept could be read deep to shallow
or left to right or right to left
So, let's say Jefferson is the #1 read
on a 7-step drop, if Stafford does not
like the protection or feels rushed he
may not want to take that shot
so maybe the deep route is what they
wanted but because line stinks
he comes off the #1 and goes to #2
which in this made-up scenario could
be Kupp or Higbee--a shorter route.
In others words maybe he was open
enough - - but not open enough to risk
the throw given the pressure situation
Just a guess
